Thank you for your feedback. But in case of individuals, partners or very small company, which format do you think is easier to remember for clients, more handy, looks best, etc.?I am not talking from a system administrator's point of view, but from the end user's only.For example, some people do not recommend using dots ("."), because they can be forgotten or be not very visible in hyperlinks with some fonts, etc.Others suggest the shorter the better; others do not recommend using "jsmith", because with some names the result/association could end up being "weird", etc.I meant stuff like this. Thanks.So, what do you think?
